What is online activism? Online activism is a type of activism that takes place on the internet, often through social media. It can take many forms, from raising awareness of a cause or issue, to organizing and mobilizing people around a shared goal. Online activists often use the power of the internet to reach a large audience quickly and efficiently.While online activism can be very effective in raising awareness and bringing people together, it is important to remember that not all online activity is considered activism. For example, simply sharing a link to an article about an issue you care about is not necessarily considered online activism. To be considered online activism, there usually needs to be some sort of call to action or attempt to bring about change.
